Find a cutter or a glass that will cut a pastry circle to fit the indent of the tray and come up the sides, and one that will make a top. Cut out your pastry shapes and rest them in the fridge.
Filling
1 Pick over 300g of spinach, remove the stems and wash thoroughly. Drain off the excess water from rinsing.
2 Cook off with a tablespoon of butter or oil to wilt down, season well with salt and pepper. Drain on a paper towel and then chop up the cooked spinach.
3 Whisk together 5 whole eggs, a cup of cream and ½cup of grated parmesan cheese. Season with salt and pepper.
4 Drop a teaspoon or more of the chopped spinach into each pastry case.
5 Put the egg/cream parmesan mix into a spouted jug and carefully pour this over the spinach-filled pastry cases until they are just full.
6 Put into the middle rack of a moderate oven and bake until they are set and look appetising.
Hint: Little pies and quiches can be made ahead and warmed to serve.
